Today, security researcher Jonathan Leitschuh has publicly disclosed a serious zero-day vulnerability for the Zoom video conferencing app on Macs. He has demonstrated that any website can open up a video-enabled call on a Mac with the Zoom app installed. That’s possible in part because the Zoom app apparently installs a web server on Macs that accepts requests regular browsers wouldn’t. In fact, if you uninstall Zoom, that web server persists and can reinstall Zoom without your intervention.
Jake Moore, Cybersecurity Specialist at ESET:
“With the possibility of malware being able to attack a webcam at any moment without the correct service patch or up to date antivirus, it is imperative that users cover their camera up at all times when not in use. Whether you have installed the Zoom application or not, webcam covers are cheap and extremely effective. Failing the use of a webcam cover, blue tack or duct tape is just as effective and could help prevent attackers from viewing you and your surroundings should any malicious software get onto your computer.”
